7 Claims.

This invention relates to tourniquets.

The main object of the invention is to provide a. device of this kind which is very simple. ea.sily applied to the limb of the patent and extremely efiective.

Another object of the invention is to provide a device of this kind which will partially constrict a limb 01 a patient so as to make the veins below stand out prominently for making a, medica] test.

Another object of the invention is to provide a. device of this kind ha.vng means to regulate the pressure of the gripping members exerted on the limb.

Another object of this invention is to construct the gripping members so that they will not out or pinch the flesh 01 the patient.

Stil] a, further object of the invention ls to provide a. ratchet mechanism for holding the gripping members in the desired locked position.

Other objects will appear as the disclosure progresses. The drawing is intended to mere1y indicate a possible embodiment 01 the invention. It is obvious that the actual needs of manuacture may necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment illustrated but rather to deflne such limits in the appended claims.

For a. more general understandlng the 1nvention attention is called to the drawing. In the drawing llke reference chara.cters denote 1ike parts throughout the specification.

In the drawing:

Fig. 1 is a. front view of the tourniquet;

Fig. 2 is a sectlon substantially on line 2-2 01 Fig. 1;

Fig. 3 is on enlarged section substa.ntially on line 3-3 01 Fig. 1;

Fig. 4 la a, section on line 4-4 of M3. 1;

Fig. 5 is a front view of a modifled form of the invention;

Flg. 6 s a, section on line 6-6 01 Fig. 5; and

Fig. 7 is a. section substantially on line 'I 'I 01 Fig. 5.

Referring now to the dra.wing in deta.il, numera.ls I and 2 designate a. set 01 complementary members hnged together by the screw 3.

Each 01 sad members comprises a. handle porton 4 and 5 terminatlng a.t the bottom 1nto eyes l and 1 for the insertion 01 the fingers of the operator and at the upper ends into curved grpping members 8 and 9 adapted to flt the Iimb o! the patient.

It will be noted by referrlng to Fig. 1 that the inside curvature 01 the tip portions IO end I I and the butt portions 25 and 26 01 the gripping members extend In a reverse directon to the curvature of the ntermedate sections thereof. The tip portions and the butt portions are a.ccordingly spaced away from the limb a.t these points when the clamp is appled so as not to pinch the flesh 5 or skn of the patient.

Attached -to the handle 4 is an arc-like ratchet l2 ada.pted to cooperate with the handle 5 for the purpose of Iocking the instrument around the limb of the patient. As noted in Fig. 3 the 0 ratchet is provided with a. series of saw teeth which engage with the handle 5. The perpendicular portion l4 of the teeth as noted in Fig. 3 are somewhat inclined so tha.t the handle member will lock in place and thus avoid any accidental separation. The portion I5 of the handle 5 is somewhat thin so as to make the same resilient a.t that particular place. Normally the handle is tensioned against the ra.tchet so that it will look tself in with the ra.tchet teeth l3. Now when the said handle member is moved the resilient or thinned portion I5 wil1 allow saune to easily bend a.nd clea.r the teeth, thus ma,king' the nstrument easily operable. The gripping members 8 and 9, as shown in Fig. 3, are preferab1y wide and someWhat flexible so a.s not to pinch the tissues or out the flesh. If desired, they can be covered up with rubber hose to give to the sad members 9. pliable efiect.

The modified form of the invention shown in Fig. 5 is the same as that shown in Fig. 1 with the exception tha.t the gripping member I6 leading from the complementary member H E made stra.ight while the gripping member IO leading from the complementary member l9 is curved 36 simlar to the member 9. Numeral designates the pvoting screw connecting the two complementary members II and |9 together, 2| and 22 the eyes and 23 the arC-shaped ratchet for regnlatng the openlng of the gripPing members and 40 keeping them in a. set positon. 'I'his form. of the invention is ma.nly adapted for opera.tng on patents when lying in bed. 'I'he stra.ight gripping member |6 can easily be pushed underneath the patients a.rm or leg without dsturbing a.nd wlthout the necessity of raising hs limb.

It will thus be seen that I ha,ve provided a. simple and efflcent tournlquet which is easy to operate and which w111 not annoy or disturb the patient. The device can be manlpula.ted with the fingers of one band only a.nd locks itself up automatically in place. By movng the two eyes together the two grlpping members will simultaneously move together and vice versa, when the eyes are separated the grpping members will move away from eanh other.

Having described my invention, I cla.im:

1. In a. device of the class descrbed, the combinaton of two complementary members pivotally fastened together, gripping members formed at the upper part of sa.id complementary members, one of said gripping members being straight and the other of sa.d members being curved Outwardly, handles at the lower ends of said. complementary members, and mea.ns to fasten sa.id handles together in a. variety of positions.

2.
